sigma T H E R M®- P is a Food Grade synthetic organic heat transfer fluid. Application : Indirect closed heat transfer systems from (– 94) °C to 230 °C in liquid phase. Without pressurization of system up to 170 °C and with proper pressurization up to 230°C. This single fluid is used for challenging requirement of Pharmaceutical, Fine Chemicals and other industries where two different circuits with different fluids are there for cooling and heating purpose. Formulation of sigma T H E R M®- P is based on all ingredients complies with US FDA, chapter 21 CFR, 178.3570 , HT1 category. Benefits : • Eliminates duel fluids for heating and cooling. • Long Life. • Cost Effective Solution • Trouble free operation • It replaces traditional duel steam & glycol or steam & brine systems. Gasket Material Compatibility : sigma T H E R M®- P has an acceptable compatibility when used within the temperature and pressure limitation of the following polymers or gasketing materials: Acetal, Aramid Fiber, Chemraz (FFKM), Epoxy, Fluorocarbon (FILM), Fluoroelastomer, Glass Fiber, Gylon, Kalrez, PEEK, PTFE, Teflon (All) , PTFE Silicon, PTFE Viton, PTFE Fiberglass, Kel-F (CTFE), Viton Composition 100 % Synthetic Appearance visual Clear Water White Colour ASTM D 156 30 Max.
